In 2024, the maximum average temperature in the contiguous United States reached nearly 20 degrees Celsius. Several of the warmest years on record have all been recorded within the last decade. Just one-degree of warming is significant, as it takes a vast amount of heat to warm up the oceans, atmosphere, and land to this degree.
